I must say that i asked also in another forum where i got murmured that i did not search in google for a solution and that there were thousands of them. I want to say that as a non experienced computer user its quite harder for me to figure out which removal guide is going to be helpful and which is just going to lead to other problems. That's why i prefer sharing my problem with people who are willing to take some time and help me. And for answering me i'd like to thank you and ssc456 also.

So anyways, on the second link someone also suggested the same program as cottonball, so i downloaded it. I also downloaded an antimalware program Malwarebytes, l'm not sure if its trusty but its free and many people recommend it.
I am now going to do a full scan of my computer, so wish me luck and thanks one more time

cottonball, thank you for the warning about ComboFix. I've heard from a friend that he had some problems with it also.
You really seem know what you are talking about.
Are you a programmer or something?
